A phenomenological description of BslA assemblies across multiple length scales.
Bottom Line: Here we describe several self-assembled structures formed by BslA, both at interfaces and in bulk solution, over a range of length scales spanning from nanometres to millimetres.First, we observe transiently stable and highly elongated air bubbles formed in agitated BslA samples.Second, we describe elongated tubules formed by BslA interfacial films when shear stresses are applied in both a Langmuir trough and a rheometer.

Mentions: To further image the tubule structures, we chemically cross-linked the film using glutaraldehyde. The cross-linked structures were then lifted onto an SEM stub for imaging. Figure 8a shows a tubule imaged using the SEM. From this image, it appears that the tubule consists of a rolled and hollow piece of film.Figure 8.
